CABLE-G RIP.

SPECIFICATION forming part of Letters Patent No. 698,842, dated April29, 1909.

Application filed October 18, 1901. Serial No. 79,178, (No model.)

in Cable-Grips; and we do hereby declare the following to be a full,clear, and exact description of the invention ,such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in cable-grips.

The object of the present invention is to simplify and improve theconstruction of grips for mining-cars and the like and to increase theirdurability and efficiency and at the same time to enable them to beoperated with great rapidity in engaging and releasing a cable.

Another object of the invention is to provide a device which will enableany of its parts when worn to be readily removed without discarding therest of the device.

The invention consists in the construction and novel arrangement andcombination of parts,hereinafter described illustrated in theaccompanying drawings, and pointed out in the appended claims.

Referring to the drawings, Figure 1 is aside elevation of our improveddevice, and Fig; 2

is a sectional view taken on line w a; of Fig. 1.'

Referring to the drawings, 1 designates a frame or body having its lowerend bent upwardly to form a stationary jaw 2, with a curved hooked lowerend and having its upper end provided with a shoulder 3, havinganinternally-sorew-threadedopeningthrough which passes a screw-bolt 4,which is adapted to be rotated to open and close a movable jaw 5, whichcooperates with the stationary jaw 2.

The lower surface of the movable jaw is concaved, as at 6, so as toreceive the upper side of the cable snugly therein.

7 designates a plate secured to the upper side of the jaw 5 byvertically-arranged screwbolts 8.

Within the frame or body 1, intermediate its ends, are provided a pairof vertically-arranged guide-slots 9 9, which are engaged by a pair ofhorizontally-disposed bolts 10 10, which pass through the movable jaw 5,by

which means the movable jaw is prevented from moving laterally. The freeends of the bolts 10 10 are provided with securing-nuts 11 1l=or othersecuring means.

The lower end of the screw-bolt 4 passes through and is swiveled in acentral opening 12 int-he plate 7 and has its lower end provided withanut, linchpin, or other securing means. In the drawings I have shown alinchpin 13 as the securing medium, and in order that the nut can beinserted in position or removed the lower portion of the platesurrounding the central opening 12 thereof is cut away to form anelongated slot 14.

The shoulder 3 is provided with an open= ing adapted. to receive acoupling device 15,

consisting of a looped bar having its inner ends provided with eyes 16,adapted to receive a coupling-bolt 17, which is screw-threaded toreceive a nut 18, whereby the coupling device is detachably secured tothe said eye.

19 designates a clevis having its ends provided with eyes for thereception of the coupling-pin 20, which is adapted to be secured to thecar.

In order that the screw-bolt 4 may be operated from the car, we provideits upper end with an eye 2l,which can be readily engaged by a lever 22,so as to rotate the said screwshaft.

The invention has the following advantages: The grip, which is simpleand inexpensive in construction, is positive and reliable in operation,and by means of the coupling-100p between the car and cable the cars areenabled to be hauled equally as well downhill as uphill. The jaws arereadily adjusted to grip the cable and the parts when worn can bereadily replaced without discarding the rest of the device.

Although we'have shown the preferred form of our invention herein, wereserve the right to make such changes in the form, proportion, size,and the minor details of construction within the scope of the appendedclaims without departing from the spirit of this invention.

We claim- 1. In a cable-grip, the combination with the body portionthereof having vertical slots therein, a screw-threaded shoulder, astationary jaw having at its lower end a curved too hook, a movable jawconnected to the slots having a concaved lower surface and an elongatedslotted upper surface, a detachable plate secured to the movable jawover the slotted plate, a screwbolt coacting with screw-threads of theshoulder and with the detachable plate, and a head at the lower end ofsaid bolt seated in said elongated slot,substantially as specified.

2. In a cable-grip, the combination with the body portion thereof havingvertical slots therein, a screw-threaded shoulder at the upper end ofthe body portion, a stationary jaw secured to the shoulder havingvertical slots and a curved hooked end, of a movable jaw connected tothe slots of the stationary jaw and having a concaved lower surface andan In testimony whereof we afiix our signatures in presence of twowitnesses.
